I’ve done all of that as stated in my first post. No charred paint. Ive removed the exhaust/carb housing go service the carb but didn’t pay particular attention to the water passages. I’ll have to pull it off again. As for the grommmet I don’t see one. There was a rubber piece that came from the water tube that was all buggered up, I trimmed a bit and can see the tube so it’s not blocked by anything.
